Coercivity of Sintered NdFeB Magnets

Department of Material Science and Engineering

摘要: 根據TEM觀察,建立了三元燒結NdFeB系永磁體的顯微結構模型。運用微磁學理論對矯頑力模型作了計算,并討論了Nd₂Fe₁₄B晶粒和NdFeB系永磁體的矯頑力。提出了燒結NdFeB系永磁體Nd₂Fe₁₄B晶粒的外延殼磁硬化理論和提高其矯頑力的途徑。

Abstract: Based on the observations of TEM, a microstructural model of Sintered NdFeB magnets has been found. The coercivity of the model was calcu-latedbased on micromagnetic theory and the coercivity of both Nd₂Fe₁₄B grains and sintered NdFeB magnets were analysed and discussed. A magnetic hardering theory of epitaxial layer of Nd₂Fe₁₄B grain and the way of increasing coercivity of sintered NdFeB magnets were put forward.
